Abstract
A technique forms contents of a deduplication container from a standalone container file system stored on the same data storage array on which the deduplication container is stored. Such a standalone container includes a container file which is formed by standalone blocks that are not shared with any other file within the standalone container outside of snapshots of that file. The standalone blocks store host data and which are hierarchically related to each other. Upon receiving a deduplication command, the storage processor carries out a set of deduplication operations which include creating and storing the deduplication container in the data storage array. The deduplication container includes container files which are formed by deduplication blocks storing the host data and which are hierarchically related to each other.
